PDF G(r) of TiO2 nanoparticles fitted by the anatase-type structural model. Firstly, (a) and (b) show the results based on the uncorrected data in the range 1.5–20 Å and 80–100 Å in interatomic distance r, respectively. Secondly, (c) and (d) show the results based on the corrected data in the range 1.5–20 Å and 80–100 Å in r, respectively. Reliability factors Rw and the difference between observed and calculated PDFs are shown at the upper right and below in each figure, respectively. |
